摘　　要：自制一支具有醌式平面结构的N-甲基靛吩咛染料D1,探讨其光谱吸收特性及染料分子共平面性对涤纶织物染色性能的影响,并研究染料D1上染涤纶过程中的染色热力学与动力学特征。结果表明:当染料用量为1%owf时,染料D1对涤纶织物染色的上染率为81.0%,K/S值为10.5,染后织物的耐皂洗、耐摩擦和耐升华色牢度均达到4级以上;染料D1对涤纶织物的吸附等温线符合Nernst热力学吸附模型,当染色温度从120℃上升至130℃时,染料D1的亲和力随之增大了2 kJ/mol,而C.I.分散蓝56的亲和力仅增大1 kJ/mol;染料D1对涤纶织物的染色符合准二级动力学模型,在130℃下,染料D1扩散速率较C.I.分散蓝56更快,且染料D1的扩散系数随着温度的升高明显增大,而C.I.分散蓝56的扩散系数变化不明显。A N-methyl indophenine dye D1 with high quinoid plane structure was synthesized,and its absorption property and the effect of coplanarity of dye molecules on dyeing performance of polyester fabrics were investigated.Dyeing thermodynamics and dynamics of D1 dyed on polyester were studied.The results showed that when the dosage of dye was 1%owf,the dye uptake of polyester dyed with D1 was 81.0%and the K/S value was 10.5.The soaping,rubbing and sublimation fastness of dyed fabrics were all above Grade 4.The adsorption isotherm of D1 on polyester fabrics was in line with Nernst thermodynamic adsorption model.The affinity of dye D1 increased by 2 kJ/mol as the dyeing temperature rose from 120℃to 130℃,while the affinity of C.I.disperse blue 56 increased by only 1 kJ/mol.The dyeing of dye D1 on polyester fabrics conformed to the pseudo-second-level kinetic model.At 130℃,the diffusion rate of D1 was faster than that of C.I.disperse blue 56,and the diffusion coefficient of dye D1 increased obviously with the temperature rose,but the diffusion coefficient of C.I.disperse blue 56 did not change significantly.
